{"abstract":"This document proposes both substantive and minor revisions to the Motor Vehicle Inspection/Maintenance (I/M) requirements to provide additional flexibility to state I/M programs by allowing such programs to replace traditional I/M tests on model year 1996 and newer vehicles so equipped with a check of the onboard diagnostic (OBD) system. Additionally, the proposed amendments would: extend the deadline for beginning OBD inspections from January 1, 2001 to January 1, 2002; revise and simplify the failure criteria for the OBD check; address State Implementation Plan (SIP) credit modeling for the OBD check; allow for limited exemptions from some OBD check failure and/or rejection criteria for certain model year vehicles; and correct a typographical error in the current basic I/M performance standard regarding OBD-I/M vehicle coverage. Lastly, this document solicits public comment on how to address the issue of repair waivers for OBD- equipped vehicles and the possibility of extending the deadline for implementing OBD-I/M checks even further.","action":"Notice of proposed rulemaking.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2000/09/20/00-24048.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"51","title":40},{"chapter":null,"citation_url":null,"part":"85","title":40}],"citation":"65 FR 56844","comment_url":null,"comments_close_on":"2000-10-20","correction_of":null,"corrections":[],"dates":"Written comments on this proposal must be received no later than October 20, 2000.","disposition_notes":null,"docket_ids":["FRL-6871-4"],"dockets":[],"document_number":"00-24048","effective_on":null,"end_page":56856,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2000/09/20/00-24048.xml","html_url":"https://www.federalregister.gov/documents/2000/09/20/00-24048/amendments-to-vehicle-inspection-maintenance-program-requirements-incorporating-the-onboard","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/00-24048?publication_date=2000-09-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2000-09-20/00-24048/mods.xml","not_received_for_publication":null,"page_length":13,"page_views":{"count":79,"last_updated":"2026-10-24 14:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2000-09-20/pdf/00-24048.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2000-09-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2000/09/20/00-24048.txt","regulation_id_number_info":{"2060-AJ03":{"issue":"200010","html_url":"https://www.federalregister.gov/regulations/2060-AJ03/amendments-to-vehicle-inspection-maintenance-program-requirements-implementing-the-onboard-diagnosti","title":"Amendments to Vehicle Inspection Maintenance Program Requirements Implementing the Onboard Diagnostic Check; Proposed Amendment to the Final Rule","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200010&RIN=2060-AJ03&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AJ03"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":56844,"subtype":null,"title":"Amendments to Vehicle Inspection Maintenance Program Requirements Incorporating the Onboard Diagnostic Check","toc_doc":"Motor vehicle inspection/maintenance program requirements; onboard diagnostic check","toc_subject":"Air quality implementation plans:","topics":["Administrative practice and procedure","Air pollution control","Carbon monoxide","Confidential business information","Environmental protection","Imports","Intergovernmental relations","Labeling","Lead","Motor vehicle pollution","Nitrogen dioxide","Ozone","Particulate matter","Reporting and recordkeeping requirements","Research","Sulfur oxides","Volatile organic compounds","Warranties"],"type":"Proposed Rule","volume":65}
